Things to know about air filters

There are many options for air filters available on https://www.amazon.com/BNX-20x20x1-MERV-Filter-Pack/dp/B09XC3RQ3J. They can be made from fabrics or fiberglass. They are rated according the efficiency of their use using the Minimum Efficiency Reporting Value (MERV), which was developed by American Society of Heating and Refrigerating Engineers. The MERV rating, a numerical value, tells you how efficient a particular filter.

Fiberglass filters are the most popular type. They’re made of layered fiberglass fibres. The fiberglass is reinforced with a metal grating to prevent it from collapsing and letting dust into the air. Fiberglass air filters are both the most economical and the least efficient of all types. These filters are usually disposable. Next are pleated or polyester air filters. Both types have similar construction, but polyester and pleated filters are more effective at stopping dust.

Their effectiveness

There is an ongoing debate about the effectiveness of HEPA filters and other air filtration technologies. However, these products do have some benefits. People with asthma may be able to benefit from a reduction in airborne particles, including PM. Studies have shown that these air cleaners reduce airborne particle concentrations by 30 to 70 percent. However, the effectiveness of these devices varies widely, depending on the size fraction and the activities of the home occupants.

Costs

Many factors influence the cost of air filtering. The filter life expectancy is the most important factor that has not been documented. The lifetime of an air filter depends on the dust concentration in the air. For a comprehensive economic analysis of air filtration, operational costs should be included as well.

In addition to operating costs, air filtration systems can also increase energy bills. The energy used by fans is estimated to consume 14% of the electricity used in industry. Reliable HVAC systems can help lower energy costs and prolong filter life. Moreover, regular replacement of filters can help reduce energy costs.
